Receipts are required for registration fees, airfare, lodging, and car rental expenses regardless of the amount. Approvers will review the receipts to ensure that it was actually the traveler who paid for the expense and that non-business related charges (i.e., hotel spa services, child car seat rental, etc.) are not included. Receipts are also required for any expense of $75 or more. Auditors expect to see receipts to support the payment of a business expense; if a payment is not proven to be business related, it may be disallowed and, as a result, taxable. It is always in the traveler’s best interest to keep records of expenses incurred and reimbursed.
